What is the difference between lens materials and why does it matter?
Also known as plastic, these lenses have excellent clarity, and are very economical. It is the least efficient of the materials, which means large prescriptions will be very thick, and there can be significant distortion when looking to the side.
This lens material is thinner than CR-39, lighter in weight, and is shatter resistant (NOT shatter proof). It is recommended for children's glasses for safety reasons. Although some people notice slight color aberrations (a subtle rainbow effect) this lens type is better than CR-39 for large prescriptions when looking to the side.
Lighter and clearer than polycarbonate, trivex is an excellent option for those who have high vision demands, like long hours on the computer and small print such as blueprints or schematics. The lens thickness is similar to polycarbonate, as is the ability to resist shattering, but this lens is not generally used in childrens' glasses.
This lens is similar in clarity to Trivex (better than polycarbonate) and is thinner.
This material is thinner than 1.60, but has worse clarity, similar to polycarbonate. In some cases, it may be worth the trade off with extremely large prescriptions.
One of the thinnest lenses on the market, it has clarity similar to polycarbonate. The cost is significant, and is typically reserved for the highest prescriptions.
If one prescription doesn't work at all distances (typically for those 40+) there are many different lens solutions. Listed are the options we offer.
From a 28 mm half circle to a complete half lens, this is a less expensive option for those on a budget or who have difficulty adapting to progressive lenses. It is best for patients don't have significant vision needs at 2 feet (arm's reach or computer distance) or those with low add (bifocal) powers.
If you have a bifocal power over +1.75 and need to see clearly both at 2 feet and up close at reading distance, this may be an option for you.
Standard progressive lenses are cosmetically more appealing than lined bifocals and trifocals. They transition smoothly from the distance vision power to the reading vision power. The downside to standard progressives is the mid-range and reading areas are often very narrow with a larger area of peripheral distortion. As with all multifocal lenses, computers set at eye level can be difficult to see.
These premium lenses have wider mid-range and near areas, and are customized to the frame style and vision needs of the patient. Patients tend to adapt to these lenses well and have fewer issues with reading and computer vision.
Various add on features that improve the functionality of your lenses.
Have you ever noticed the shiny reflections off of your lenses, or took a picture and your glasses acted like a mirror and you couldn't see your eyes? This feature adds comfort, clarity, and comes with a scratch warranty. We recommend them on all eyeglasses.
This is a design that optimizes clarity, especially in large prescriptions.
Some patients prefer this feature as it may reduce eye strain from digital devices, and it protects the eyes from some wavelengths of UV light. If your glasses are photochromic, this is typically not necessary.
These are the lenses that typically darken under UV light. The basic photochromic is typically clear indoors and a medium dark shade outdoors.
The medium grade has a light tint indoors but gets a much darker shade outdoors.
The premium photochromic lenses darken in ambient light, even indoors. These are the only photochromic lenses that will significantly darken inside of a vehicle, and are excellent for patients with extreme light sensitivity.
